Hi, SkitsDoubt. It does seem like some professionals are close-mouthed. I didn't find out my first therapist had diagnosed me with borderline personality disorder until years later. I also wasn't told about my Generalized Anxiety Disorder. I think I saw it somewhere. But I was told about Bipolar during my first hospitalization, though.
I only remember one hospital where patients were sat down and told what their diagnoses were!
It'll be interesting to see if other people's experiences are like ours.
